Undercutting
A cylindrical hole is drilled and then conically undercut in one step with only one tool.
Different levels of automation are possible depending on machine type and material.
The drilling time in ceramics is less than 10 seconds.
Panels of any size or weight are given an undercut of precise and uniformly symmetrical shape.
hole Ø 7 mmundercut Ø 9 mm
To prepare for installation, an undercut anchor is inserted into the hole and tightened to a positive t using a screw.
Quick, simple and safe with normal tools, e.g. a cordless screwdriver.
Safety and product liability require that the KEIL undercut attachment system is always used as a unit. Correct functioning is ensured only if matching KEIL products (anchor with screw or threaded pin, drill head and facade drill bits) are used together. Their use as a system has also been stipulated in the approvals granted and applied for. The compo-nents of the KEIL undercut attachment system are protected by patent.

The KEIL undercut anchor, for invisible attachment of thin panels, is manufactured from stainless steel. Its geometry, matched to the KEIL undercut hole, applies maximum loads to the panels in an optimum manner. This geometry ensures stress-free attachment in all commonly used panel materials from 6 mm thickness. Depending on panel thickness or carrying capacity required, different insertion depths (hS) are available. The KEIL undercut anchor is designed in such a way that it withstands a greater load than just the weight of the panel. The KEIL undercut anchor offers major bene ts due to the high installation integrity. The anchor is placed quickly, easily and safely at a controlled depth for all panel thicknesses in an optimum installation by using matching KEIL system components: anchor, panel bracket and KEIL locking screw with integral locking mechanism. Only two parts (anchor sleeve and screw) are required for safe attachment. Additional screw-in parts for the KEIL undercut anchor provide individually tailored connection options, such as
hS = 4,0mm hS = 5,5mm hS = 7,0mm hS = 8,5mm
hS = 10,0mm hS = 11,5mm hS = 13,0mm hS = 15,0mm
Connection to a support structure Connection to a cassette structure Attachment of sof t panels with internal angles Direct attachment to a wall using fork anchors or plug-in anchors
Attachment of wash hand basins, countertops, furniture, grave surrounds or natural stone radiators

Approvals of the KEIL KH undercut anchor (as at 1/2013)
Approvals can be provided on request.
KEIL undercut anchors are monitored by third parties.If required, a certi cate of conformity may be requested.
SpacerInsertion depthApproval hS=4 hS=7hS=5,5 hS=8 hS=8,5 hS=10 hS=11,5 hS=13 hS=15
Highest safety due to many patents and approvals, for example the European Technical Approval (ETA) for the attachment of facade panels (see above).
A complete system – technically mature and proven innumerable times. Facade panels as thin as 6 mm – economic and saving resources. Installation independent of temperature and climate with a high degree of pre-assembly in the factory or on site.
Position of undercut anchor on the back of the panel can be selected without constraints.
Tolerances in panel thickness are simply compensated for by means of spacers.
Earthquake tested up to magnitude 9.4 on the open-ended Richter scale. Very high load capacity due to optimum load application, but without stressing the facade panel by lateral bracing = positive t.
Breakage loads are up to seven times higher than for edge attachment (e.g. bolt anchors).
Subsequent replacement of individual or all facade panels. Non- ammable, mechanical and permanently safe attachment

There are no limits to creativity. Whether elegant, traditional, modern, delicate or unconventional – even the boldest facade designs can be implemented.
A clean facade undisturbed by visible attachment points. More than 50 different panel materials are available: e.g. ceramics/ ne stoneware, natural stone, plastics/HPL,
bre cement, glass bre reinforced concrete, ceramic glass, arti cial stone, glass. The combination and interaction of different materials, shapes and colours is possible and helps to achieve the effects planned.
Closed or open joints without visible anchors are characteristic for high-quality facades. No dirt or rust streaks as the attachment components are situated at the rear. Long life and low maintenance costs. Larger panels than for attachment at the edge for the same safety level. Increase in the value of the building with regard to acceptance and marketing.

Undercut anchor KH AA
The undercut anchor consists of an anchor sleeve and its hex screw. Hole, anchor sleeve and screw length have to be matched to the hole depth required and to the panel bracket chosen. Only the use of matching components results in quick, simple and safe installation.
The anchor sleeve, which is compressed in the lower end, is placed in the hole with the speci ed panel bracket.
The screw is screwed in while exerting slight pressure on the panel bracket (to x the anchor). The locking mechanism of the screw cuts into the panel bracket to secure it.
The panel bracket forms a rigid unit with the KEIL facade anchor for this type of installation. The anchor sleeve is expanded to its original dimension by inserting the screw to a controlled depth, so that the sleeve sits snugly against the undercut section of the hole in the facade panel. After installation, the anchor sits stress-free in the undercut hole (i.e. the bracket can still be rotated with a certain amount of effort).

FOGeneral installation instructions
The undercut holes on the back of the facade panels must be made using KEIL System tools under workshop conditions.
The KEIL System tools comprise the KEIL facade drill bit, the KEIL drill head and the undercutting and drilling machine (e.g. KEIL porta-ble drill, KEIL bench drill or automatic drilling machine with KEIL drill head).
The undercut hole is produced in one step (cylindrical drilling [1] and undercutting [2]).
Correct installation of the undercut anchor is possible only if a precisely undercut hole exists [3]. The hole geometry is regularly monitored with the KEIL gauge matching the insertion depth of the anchor. The hole depth is set by means of this gauge, and all major hole dimensions can be checked ef ciently with it.
The undercut anchor consists of an anchor sleeve and its hex screw.
Hole, anchor sleeve and screw length have to be matched to the hole depth required and to the panel bracket chosen. Only the use of matching components results in quick, simple and safe installation.
The anchor sleeve, which is compressed in the lower end, is placed in the hole with the speci ed panel bracket [4].
The screw is screwed in while exerting slight pressure on the panel bracket (to x the anchor) [5]. The locking ratchets of the screw cuts into the panel bracket to secure it.
The panel bracket forms a rigid unit with the KEIL facade anchor for this type of installation.
The anchor sleeve is expanded to its original dimension by inserting the screw to a controlled depth, so that the sleeve sits snugly against the undercut section of the hole in the facade panel. After installation, the anchor sits stress-free in the undercut hole (i.e. the bracket can still be rotated with a certain amount of effort).

Roller conveyor drilling table KRT
Drilling table with roller conveyor KRT
Drilling machine for the ef cient manu-facture of KEIL undercut holes for use in workshop and on site (total weight approx. 90 kg). The multidirectional roller conveyor (1,500 mm x 600 mm) with pneumatic panel clamping unit and attached KSDV or KSHV portable drill provides excellent handling, simple operation and fast chan-geover to different hole spacings. After setting the insertion depth hS, panels of different thickness can be drilled without further adjustment.
The depth of the undercut hole may be con-stant either to the front or rear of the panel. For undercut holes which are constant to the front of the panel, the conversion kit for front face controlled drilling has to be tted. The undercutting drilling machine can be removed and used with the vacuum foot (without roller conveyor).
